When you open File Explorer or Windows Explorer, it will display a preview of images in the thumbnail format. If you carefully notice, the thumbnail preview has an almost minimal border, but this can be changed. You can apply different types of borders can be applied to thumbnails. It includes No border, Straight border, Photo Border, and Shadow border. In this post, we will show how you can change the border of Thumbnail Preview in Windows 11/10/8/7.
Note: In Windows 7 and Vista, the default Thumbnail Preview is the Miniature Photographs. If you don’t like it, you can change it to No border or Straight border for the minimal looks.
Change Border of Thumbnail Preview in Windows 11/10
The default Thumbnail Preview Border appears as Miniature Photographs (Windows 7) or Straight border (Windows 11/10). You can, if you wish, tweak the registry to make them seem like a video film cutting along with the ‘sprocket-holed’ perforated borders. It is also called as the Photo border. Here we will use the registry method to tweak the thumbnail preview.
- To do so, type ‘Run’ in the Start menu search bar or use Win + R.
- Then, in the ‘Run’ dialog box type ‘Regedit’ and hit enter.
- It will open the Registry Editor. Navigate to the following key:
HKEY_CLASSES_ROOT\SystemFileAssociations\image
- In the right panel, right-click on Treatment and select Modify. Change the hexadecimal value of this to 3, from its default 2.
- You can then either choose to reboot or restart Windows Explorer by killing it from the task manager or in Windows 10; you have the Restart option.
Open any folder where you store your images and ensure that the thumbnail view is selected. You should notice the change. You can also apply the values 0 and 1, but they don’t make any substantial visual difference. If you find using the registry editor difficult, then you can also use Ultimate Windows Customizer or Ultimate Windows Tweaker to do it quickly.
While it’s only a minor tweak and not many people would like to change it, but if you are a fan of those film strips, you still have the feature. I hope the post was easy to follow, and you were able to change the thumbnail preview border in Windows in File Explorer.
